Your Car Not Starting: Things to Check Before Calling the Mechanic

409

 

Experiencing a car that won’t start can be frustrating and inconvenient. While it may be tempting to immediately call a mechanic, there are several common issues that can be easily diagnosed and fixed without professional assistance. In this article, we will discuss some essential checks you can perform before reaching out to a mechanic, potentially saving you time and money.

Battery
The battery is often the culprit behind a car’s failure to start. Begin by checking the battery connections to ensure they are clean and secure. Corroded terminals can prevent the flow of electricity, so if you notice any build-up, clean it using a battery terminal cleaner. If the connections are fine, test the battery voltage using a multimeter. A healthy battery typically reads around 12.6 volts. If the voltage is significantly lower, the battery may need to be charged or replaced.

Ignition Switch
Faulty ignition switches can prevent power from reaching the starter motor, resulting in a no-start condition. To test the ignition switch, turn on the headlights. If they are dim or flickering while you attempt to start the car, it could indicate a problem with the switch. Try jiggling the key in the ignition to see if it affects the connection. If there are signs of a malfunctioning ignition switch, it’s best to have it replaced by a professional.

Fuel System
If the engine cranks but fails to start, the issue may lie within the fuel system. Start by checking the fuel level in the tank. It may seem obvious, but sometimes a low fuel level can cause a no-start situation. Next, listen for a faint humming sound from the fuel pump when you turn the key to the “ON” position. If you don’t hear anything, it could indicate a faulty fuel pump. However, if you do hear the sound, the pump may still be functioning, but there could be a problem with the fuel filter or injectors. Consult a mechanic for further diagnosis and repair.

Starter Motor
A faulty starter motor can prevent your car from starting. If you turn the key and hear a clicking noise, it could be a sign of a bad starter motor. Before assuming it’s the problem, check the battery terminals for tightness and cleanliness. If they are secure and corrosion-free, tap the starter motor lightly with a wrench or a hammer while someone else tries to start the car. If it starts working, the starter motor is likely worn out and should be replaced.

Fuses
Blown fuses can cause various electrical components, including the starter motor, to fail. Locate the fuse box in your car (usually under the dashboard or in the engine bay) and inspect the fuses related to the starting system. Look for any signs of a blown fuse, such as a broken filament or discoloration. If you find a blown fuse, replace it with a new one of the same rating. However, keep in mind that a blown fuse may indicate an underlying electrical issue that should be addressed by a professional if the problem persists.

By performing these checks, you may be able to identify and fix the problem yourself or at least provide valuable information to the mechanic, helping them diagnose the issue more efficiently. If all else fails, don’t hesitate to seek professional assistance.
